WASTE-CLEANING MACHINE.

Specification of Letters Patent.

Patented July 28, 1914.

Application filed August 19, 1913. Serial No. 785,555.

To all whom it may concern lle it known that I, Gnonon \V. HAnNns, acitizen of the United States, residing at Al liance, in the county ofBoxbutte and State of Nebraska, have invented new and usefulImprovements in lVaste'Cleaning l\lachines, of which the following is aspecification.

This invention is an improved machine for cleaning and recovering waste,especially cotton waste which has been used in the journal boxes of caraxles, the object of the invention being to provide an improved machineof this character which adapted for separating the short, broken andworn pieces of waste from the longer pieces and for also removing all:t'oreign substances such as particles of Babbitt metal, dirt and thelike from the longer waste so as to recover the longer waste from theworthless particles and short pieces and enable the longer pieces to bereused, the invention consisting in the construction, combination andarrangement of devices hereinafter described and claimed.

In the accompanying drawingsz-Figure 1 is a side elevation of a wastecleaning machine constructed in accordance with my invention. Fig. '2 isa vertical longitudinal sectional view of the same. Fig. 3 is ahorizontal sectional view of the same on the plane indicated by the lineoct of Fig. 1. Fig. at is a vertical transverse sectional view of thesame.

The frame 1 01' my improved waste cleaning machine is ot oblongrectangular form and is provided with supporting legs 2 which arearranged near the corners thereof. The supporting legs are provided withbearings 23 in which are mounted the shafts l--5 of an endless carrier(3 which comprises a pair of rollers 7 on the shafts -l.--5, spacedendless bolts 8 which engage and connect the said rollers andtransversely arranged spaced flight bars 9 which connect the said beltsand the ends of which are outturned as at 10, so that the outturned endsot' the upper flight bars project upwardly, as shown in Figs. 1 and E2.

The shaft l. is provided at one end with a pulley 11. On the centers ofthe sides of the frame 1 are blocks or other suitable supports 12 whichproject upwardly therefrom and to which the ends of a bar 13 aresecured, the bar being provided with a series of transversely arrangedspaced fingers 14: which project: from opposite sides thereof. This barwith its lingers constitutes a lixed comb.

A pair of shafts 15-16 are mounted for rotation in opposite directions,are arranged on opposite sidesof and at a lower plane than the lixedcomb and are journaled in bearings 17 with which the frame 1. isprovided. lhcse shafts are, respectively, provided with spaced fingersLS-ll) which project from opposite sides thereof and are arranged topass through the spaces between the lingers oi the lixed comb, theplanes of revolutionot the said lingers jl8ll) being intersected by thelingers of the lixed comb. llach of these shafts with its lingersconstitutes a revoluble comb as will be understood. The shaft 15 has aspur gear 22 of the same diameter as the gear 20 so that the revolublocombs are caused to rotate in reverse directions as indicated by thearrows in Fig. The shaft 15 is also provided with a pulley 23 which isconnected by a belt 24; to a double pulley 25 which is mounted on a stubshaft 26, said double pulley being connected by a twisted endless belt27 to the pulley ll of the roller shaft 4. Hence, the carrier (3 is alsodriven and is caused to move, as to its upper flights, in the directionindicated by the arrow in Fig. 3.

At the ends ot the frame 1 are secured the upper sides ot a pair ofinclined downwardly converging grates 28, the bars of which are pre'lerahly made of wires or rods of suitable gage having oi'ltturned lowerends 52!) connected together by cross bars 30.

It will. be noted upon reference to Figs. 1. and 2 of the (,lrawingsthat the grates Q8 discharge at their lower ends above and upon theendless carrier (5. A. cover 32 is provided for the machine which isarranged at the lower edges of its walls to fit around and to be titledon and to be bolted or otherwise sccured to the frame '1. This cover isprovided at its center with a hopper 33.

In the operation of my improved machine, the used waste as from thejournal boxes of railway car axles is placed in the hopper 33 and dropson the lixed comb. The teeth of the revolving combs which pass downwardly and through the spaces between the teeth of the fixed comb knock thewaste from the fixed comb and separate the particles, the dirt, piecesof Babbitt metal and short, broken or worn particles of waste that dropthrough the spaces between the teeth of the combs and also. drop throughthe spaces tween the flight bars of the endless carrier while the longerthreads or ieces of waste are caught by the teeth of the revoluble combsand thrown by them on the downwardly inclined grates 28 down which theyslide and from which they drop on to the flight bars of the endlesscarrier, the said endless carrier delivering the recovered long piecesof waste at one side of the machine. The grates 28 permit such pieces ofshort waste or foreign particles as may be'in the long waste when thelatter is thrown upon said grates to drop and become separated from thelong waste so that the long waste is separated and cleaned from theshort waste and foreign particles both by the action of the fixed andrevolving combs and by the action of the inclined grates.

The revolving combs rotate at a high rate of speed so that the teeth ofthe combs serve by striking the waste to knock the particles of wasteapart and prevent them from being broken up and torn in pieces.

While l have herein shown and described a preferred form of theinvention, I would have it understood that changes may be made in theform, proportion and construction of the several parts without departingfrom the spirit of the invention and within 1' the scope of the appendedclaims.

l, ln a machine of the class described, the combination of a fixed comb,and a pair of revolving combs on opposite sides of the fixed comb, apair of downwardly converging inclined grates spaced apart and arrangedunder the revolving combs, and a carrier below and between the saidgrates and on which the latter discharges.

52. In a machine of the class described, the combination of a fixedcomb, and a pair of revolving combs on opposite sides of the fixed comb,a pair of downwardly converging inclmed grates spaced apart and arangedunder the revolving combs, and a carrier below and between the saidgrates and on which the latter discharges, the said endless carrierbeing provided with spaced flight bars.

In testimony whereof I afllx my signature in presence 01 two witnesses.
